GALVANIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 373,435, dated November22, 1887.

Application filed February 1l), 1887. Serial No. 228,205.

To @ZZ whom it may concern:

Be it known that I, HORATIO J. BREWER, of the city, county, and State ofNew York, have invented a new and Improved Galvanic Battery, of whichthe following is a full, clear, and exact description.

The object of my invention is to provide a new and improved galvanicbattery which is simple and durable in construction, effective inoperation, and not liable to be damaged.

The invention consists in the construction and arrangement of variousparts and details and combinations of the same, as will be fullydescribed hereinafter, and then pointed outin the claims. i

Reference is to be had to thc accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of .my improvement. Fig. 2 is a sectional planview of the same on the line z e of Fig. 3. Fig. 3 is a sectionalelevation of the same on the line .r 90 of Fig. l, and Fig. 4 is asimilar view ofthe same on the line y y of Fig. 2.

The cell A-of convenient shape and suitable material, such as hardrubber, glass, &c.-

is provided at its upper end with part of a cover, B, permanently fixedto the cell and preferably of the same material. In the cover B isformed an aperture, C, through which passes the positive electrode D,held at its lower end in a recess, E, formed in the bottom of the cellA, so as to prevent sidewise motion of the electrode. The positiveelectrode is thus firmly held in place in the cell A, and is provided onits upper end, which extends a short distance above the cover B, withthe usual binding-post.

In the cell A is placed in an inclined position the plate F, which iswider at the bott-om than at the top, which latter lits snugly Linder oragainst the free end of the cover B. The plate F rests with its sideedges on two adjoining sides of the cell, and thus forms twocompartments, A and A2, in the cell A. The

compartment A is closed on top by the cover B, and in it is held thepositive electrode D, and it also contains the exciting-liquid used inconnection with the battery.

In the compartment A2 is placed the nega- (No model.)

tive electrode G, provided on its upper end with the usual head, H, fromwhich projects the bindingpost I. The head H is below the upper edge ofthe cell A, so that only the binding-post I projects above the cell A.The compartment A' is filled with electro-negative material J, which ispacked upon the inclined plate F and around the negative electrode G.The electro-negative material extends to within a short distance of thelower end of the head H, and upon the top of the electro-negativematerial J is placed the cover K, of waX, ccment, or other suitablematerial, so that the head H of the electrode G is completely embeddedin the cover K.

The plate F is inclined, so as to form suffi cient room in the upperpart of the compartment A2 for the head H ofthe electrode G, and alsofor conveniently packing the electro-negative material in the space Azaround the electrode G. The inclined plate F may be of a porous carbonor other suitable material. It will be seen that only the bindingpost ofthe electrode G projects above the upper end of the cell A.

In batteries as now constructed the head or cap surrounding the upperend of the negative electrode is raised above the top of the cell andcovered with a coating of wax or cement to preserve it from the actionof the atmosphere and attack of the salts of the battery. It is liableto be broken during transportation and to have its coat-ing chipped off,thus seriously injuring the battery. In order to obviate this difficultyI embed the cap or head of the carbon electrode in the cement coverwhich seals the cell, entirely surrounding said cap with the cement andleaving the bindingpost above the top of the cell.

It will further be seen that the cement cover to my cell is so formed asto be higher in the center around the electrode G than on any other partof its surface, causing any liquid that may be spilled on the said coverto run offand escape over the side ofthejar or through the vent-holes,thus preventing the accumulation of salts in the cover.

The inclined plate F is firmly heldin its position by its upper edgeresting under or against the free end of the cover B and by the electronegative material pressing with its ICO own weight against the inclinedplate. By the construction described I provide a very effective andconvenient battery,and one which is especially adapted for medical andother uses Where a large number of small cells is required.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. In a galvanic battery, a cell having a partcover permanently secured to the cell and provided with an aperture forthe passage of the positive electrode, substantially as shown anddescribed.

2. In a galvanic battery, the combination, with the cell, of adivision-plate placed in an inclined position and dividing the cell intotwovcompartments, of which one is larger at its upper end to formsufficient space for the `head of the negative electrode and forconveniently packing the negative material around the-negativeelectrode, substantially as shown and described.

which is thus protected from evil influences substantially as set forth.

4. In a galvanic battery, the combination, with the cell and a partcover permanently secured to the upper end of the cell, of adivisionplate held in an inclined position in the said cell and restingwith its upper edge under or against the free end of the part cover,substantially as shown and described.

5. In a galvanic battery, the combination, with the cell provided with apart cover having an.v aperture for the passage of the positiveelectrode, of a division-plate held in an inclined position in the saidcell and forming two compartments, one for the positive and one for thenegative electrodes, the e1ectronegative material placed in one of thesaidv compartments," the negative electrode provided with a head heldbelow the upper edge of the cell, and a cover held on top oftheelectro-negative material and completely embedding the said head ofthe negative electrode, substantially as shown and described.
